First, you need to determine if your range temperature really is accurate or not. Please do so with an oven thermometer and take 3 readings at 15 minutes intervals .To calibrate, you will have to play with the knobs for older models. Most ranges have the calibration adjustment on the underside of the knob itself. You have to loosen up the dial plate and move it one way or the other so the temperature will change once the dial once installed. To adjust the knob setting, use two hands and, from the back of the oven knob, pull the knob off with a firm grip. Now, once off, look at the back of the knob. There are typically 2 screws that hold the face of the knob, the degree markings, in place. Have a look to see where the gage on the back currently points, which might be the center.
Using a screwdriver, you can loosen the screws so that you can twist the face of the knob and reposition the numbers to match the temperature in the oven. You’ll need to reposition the pointer on the back of the knob to be half way between the marks and to replace the knob on the oven. Other control designs have the temperature calibration screw down the center of the shaft. These usually require a special small screwdriver to access it. See below for a link to a detailed calibration method for one brand of oven thermostat. Once the adjustments are done, you can reset the oven temperature to 350 and wait 15 minutes. Note the temperature and then wait 5 minutes.
Electronic Control Calibration
The following procedures don’t apply to all range brands. Please note that some of them may require other settings. There are many exceptions and procedures vary from model to model so check your owner's manual.
If the temperature is out more than 35°F, the oven sensor or the electronic control may need to be replaced to correct the inaccuracy.
STEPS:
- Press BAKE
- Select a temperature of 550
- Quickly (within 5-seconds of setting 550) press and hold the BAKE button approximately 5-15‡ seconds until "00" or the previously entered temperature adjustment is displayed.
- Press the UP/DOWN arrow button or turn the set knob to change the oven temperature in 5° increments to a maximum of +/- 35°
